first evidence of batrachochytrium dendrobatidis in china: discovery of chytridiomycosis in introduced american bullfrogs and native amphibians in the yunnan province, china.although the chytrid fungus batrachochytrium dendrobatidis (bd), the etiological agent of amphibian chytridiomycosis, has been implicated in mass mortality and population declines on several continents around the world, there have been no reports on the presence of bd infections in amphibians in china. we employed quantitative pcr and histological techniques to investigate the presence of bd in introduced north american bullfrogs (rana catesbeiana) (referred to hereafter as bullfrog) and native ...201020372969
a family of antimicrobial peptides related to japonicin-2 isolated from the skin of the chaochiao brown frog rana chaochiaoensis.four structurally-related peptides with antimicrobial activity were isolated from an extract of the skin of the chinese brown frog, rana chaochiaoensis liu, 1946. determination of their primary structures revealed that they are members of the japonicin-2 family, previously identified only in the skin of the japanese brown frog, r. japonica. japonicin-2cha (fvlpllgilpkelcivlkknc) represented the most abundant peptide in the extract but its growth-inhibitory potency against staphylococcus aureus ( ...200616928470
